$THIEETW'MH FEWDEW SPECIFICATION forming part of Letters Patent No. 766,906, dated August 9, 1904.,

Application filed ece be 23, 1903- s fll NO- 186,390. (No model.)

To (I/ZZ 1071 0771 it puny concern:

Be it known that LEnNIs'r I:I.So1rur.zn,a citizen of the United States; residing at Kansas City, in the county of Jackson and State of Missou ri,have invented certain new and useful Improvements in Street-(Jar Fendersof which the following is aspecification.

My invention relates to street-car fenders of that type which are adapted by striking an object to be automatically set to pick up the object struck or another which may occupy the track; and my object is to produce a fender of this character which operates efliciently and reliably and is of simple, strong, durable,and comparatively cheap construction and which can be easily and cheaply applied to the approved types of street-cars now in use.

ith this general object in view the invention consists in certain novel and peculiar features of construction and combinations of parts, as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1 represents a top plan view of a fender embodying my invention, said ligure also showing a small portion of the car-truck to disclose the relation and connection be tween it and the fender. Fig. 2 is a vertical longitudinal section taken on the line H II of Fig. 1. Fig. 3 is a similar view, but with the fender in its depressed position and ready to pick up an object from the track. Fig. i is a cross-section taken on the line 1V IV of Fig. 2.

In the said drawings, 1 1 designate part of a street-car truck, and 2 the usual longitudinal side beams of said truck.

3 designates hangers depending from beams 2 and provided with a vertical series of perforations i.

5 designates a U-shaped frame having its front or bridge bar flattened and its side bars or arms circular in cross-section and terminating in vertically-flattened ends pivotally connected, as at 6, to hangers 3, the pivotbolts 6 extending through a pair of the perforations 4 of said hangers, the latter having the vertical series of holes to permit of vertical adjustment of the frame to accommodate cars having platforms of varying height.

7 designates a skeleton platform or frame of any suitable construction. and having its rear portion secured, as at 8, to the arms of the pivoted frame 5, the front portion of said skeleton frame fitting snugly within the front end of said frame and being secured by bolts 9 to the front ends of bars 10, which bars at times are runners for a purpose hereinafter explained. Said bars underlie the rear crossbar of the platform and lit in the bifurcated depending arms of angle-brackets 11, secured to said platform, this relation stiffening said. bars or runners against lateral movement. The rear ends of the bars or runners are pivotally mounted on a cross-bar 1E2, connecting the arms of the pivoted frame 5, said crossbar also giassing pivotally through openings in the arms 14: of a rock-shaft 13. shaft is journaled in the round portion of a keyhole-slot 16 in a swing-bar l5 and, in conjunction with its arms l t and bars 10, c0nstitutes a toggle connectionv between the swing bar and the pick-up frame. The swing-bar is pivotally mounted at its upper end on bolt 17, carried by bracket 18, bolted or otherwise secured to portions 1 of the truck, said bracket being arched at its middle, so as to have an extended bearing on opposite sides of the swing-bar to assist in preventing lateral movement thereof.

The swing-bar is preferably notched, as at 19, to accommodate the cross-bar 152 when the fender occupies its elevated or normal position and is provided with the keyhole-slot hereinbefore mentioned in. order that the crank-shaft may be engaged with or disengaged from the swing-bar easily and quickly, said crank-slnift being preferably formed of a single piece of metal forged with its arms 14: flattened in order that they may be readily withdrawn or inserted through said slot.

The cross-rod 12 between one of the rockshaft arms and one of the bars or runners 10 is equipped with a drum or roller 20, and extending down under said roller rearward of the platform and attached at its lower end to the rock-shaft below the drum is a chain or The rockthe upper ends of the crank-arms 27 of a.

rocking cam-shaft 26, journaled in the bars or runners below the fender-platform, the said crank-arms projecting up through the platform, as shown clearly in Figs. 1 and 2. The cam 28 of said shaft is disposed at its front side and adapted as the shaft rotates in the direction indicated by the contiguous arrow, Fig. 2, to elevate the front end of and trip the catch 29 from the cam-shaft. The catch is pivoted, as at 80, to the lower end of swing-bar 15, which bar in its normal position is pitched downwardly and forwardly at such an angle that it swings rearward to approximately the position shown in Fig. 3, when the catch is tripped from engagement with the cam-shaft.

The means for operating the cam-shaft, as explained, is a longitudinally-movable tripframe comprising front cross-bar or bumper 31 and rearwardly-projecting side bars 32, the said bars being braced, by preference, by the cross-bar 33 at a suitable point. In normal position, as hereinbefore explained, the parts of the fender are disposed, as shown in Fig. 2 most clearly. so that when an object is struck by the bumper of the trip frame the latter is forced rearwardly, this action rotating the cam-shaft in the direction indicated by the arrow, Fig. 2, so as to trip from said shaft the engaging catch 29.

Before the bumper-bar of the trip-frame has reached the front end of the pivoted frame 5 the catch is disengaged from the cam-shaft, and as a result the pivoted frame, with the connected parts, drops down upon the track, this action instantly rocking the rock-shaft in the direction indicated by the contiguous arrow, Fig. 2, so as to swing bar 15 rearwardly and pull the catch in the same direction to prevent any accidental reengagement of the same with the cam-shaft, the front end of the catch projecting forwardly beyond the cam-shaft to always bear upon the latter and being tapered, as shown, so as to insure the automatic reengagement of the catch when the fender is reelevated. as hereinbefore explained.

As the pivoted frame equipped with the platform and constituting, in effect, a pivoted pick-up frame drops the rearward movement of the trip-frame continues until eventually the cross-bar 25 slips under the spring 34, secured to the platform, said spring serving to prevent the trip-frame fromjumping forward again as the pick-up frame strikes the trackway, such forward movement being objec- 5 tionable because it would tend to throw the object caught off the front end of the frame and would furthermore be liable to injury from the weight of impact with said object. As the pick-up frame drops the bars or runners 1O strike the trackway for the purpose of holding the pick-up frame slightly off the track and trackway, so as to clear any irregularities in the latter, such irregularities, of course, as projecting paving-stones or boltheads.

From the foregoing it will be apparent that the person struck by the trip-frame would he usually knocked down upon the track and in such recumbent position would either be gathered up by the pick-up frame or would be forced by the latter off the track. After the person or object is removed from the pick-up frame the motorman by grasping the ring or handle 23 reelevates the latter, this operation first imposing strain in a forward and upward direction on the cam-shaft to disengage the cross-bar 25 thereof from the springcatch 34. It then distributes the strain on both cables or chains, the front cable or chain continuing the movement of thecam-shaft and the rear one by rolling upwardly and forwardly on the drum or roller moving the latter and the pick-up frame and swinging the rock-shaft forwardly with rod 12 as its axis of movement, which action obviously advances the lower end of swing-bar 15 and the catch until the latter by gravity reengages the cam-shaft, a flat spring 35, carried by the platform by preference, serving to press the front end of the catch downward to insure its reengagement with cam-shaft.

From the above description it will be seen that I have produced an efficient and reliable car-fender and that the same is susceptible of modification in various particulars without departing from the principle of construction involved or sacrificing any of its advantages.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is
